"The tar.gz file can be found with the pre-built images." - specified in -i.MX Linux User's Guide.
In "Freescale Yocto Project User's Guide" :
"One way to place an image on a device is to use the Manufacturing Tool, MFGTool. The recipes used to build a
manufacturing tool image are linux-imx-mfgtool and u-boot-mfgtool.
To build a manufacturing image do the following -
$ bitbake fsl-image-mfgtool-initramfs"
I did not find "pre-built itages" in my PC.
I should run the bitbake fsl-image-mfgtool-initramfs ?
